Abstract: Methods and computer-readable media for displaying two-dimensional objects on a display device are disclosed. Rendering requests are received from an application to render two-dimensionally modeled graphics to a display device. Primitive geometries of drawing calls of the rendering requests are tessellated into sequences of triangles. The vertices of the triangles are mapped to a vertex buffer along with an index to identify associated constant data. Batching operations store and communicate calls and mapped data to a graphics processing unit by way of a three-dimensional rendering application program interface. Constant data associated with the mapped data are indexed and appended together in a constant buffer, thereby allowing drawing calls to be coalesced. A staging buffer and a staging texture are provided for batching text anti-aliasing operations. Shader fragments are precompiled and organized by way of a predetermined lookup table.

Abstract: The invention relates to the field of ophthalmic systems and procedures. In particular, the invention relates to the determination of the post-operative position of an intraocular lens (termed “IOL”) in an eye of a patient undergoing lens replacement surgery, which involves determining the position of the existing crystalline lens in the pre-operative eye of the patient and using that information and a single numerical constant to predict the post-operative intraocular lens position. Related methods, and computer programs for performing the methods of the invention, are also disclosed.

Abstract: The subject disclosure relates to managing z-dimensional ordering of elements within a computing system display through the use of z-order bands. As described herein, z-order bands are utilized to arrange windows and other graphics corresponding to respective application types. A policy engine controls which windows and/or other graphical elements can enter and exit each band. Graphical elements within a given band can additionally be subject to per-band properties corresponding to the band and/or user preferences. As additionally described herein, z-order bands and/or other suitable mechanisms are utilized to facilitate registration watermarking for a computing environment by rendering a registration watermark display upon determining that one or more licensed elements of a computing system have not been registered.

Abstract: Methods and systems provide for sharing of a network resource that requires an authentication ID for access with a user not currently having an authentication ID. A placeholder is generated in an access list providing authorization for the network resource and the placeholder is associated with a known identifier of the user. Upon the user obtaining an authentication ID and attempting to access the network resource, the authentication ID for the user is stored in the placeholder to establish authorization for the user to the network resource. Several checks may be made prior to storing the authentication ID within the placeholder, including determining whether the user has verified obtaining the authentication ID with the issuer, determining whether the authentication ID of the user attempting access matches the authentication ID the issuer has provided for the user, and determining whether the known identifier stored in the placeholder matches a sign-in provided by the user.

Abstract: Methods and systems are provided for automating a request for access to computer accessible resources. If access to a computer accessible resource is denied, an automated request for access may be forwarded to a provider of the resource without the need for the requestor to know the identity and/or address of the provider. If the provider grants access to the requestor, access may be automatically granted, or access may be granted along with a notification to the requestor of the granted access.

Abstract: Methods of stimulating production of coalbed methane from a coal-bearing formation are described, one method involving providing a perforation charge comprising a standard charge portion and a charge additive able to produce localized temporary oxidizing environments in perforations; perforating a coal-bearing formation with the perforation charge to form initial perforations defined by carbonaceous material, the initial perforations having localized temporary oxidizing environments in them, and initiating combustion of the carbonaceous material using the oxidizing environments, thus enlarging the initial perforations. Other methods involve perforating the coal-bearing formation with a standard perforation charge, thereby creating perforations; and treating the perforations with a composition creating temporary local oxidizing environments involving an oxidant in the perforations, and initiating combustion of carbonaceous material using the excess oxidant, thus enlarging the perforations.

Abstract: Described is the adding of padding to a content file (e.g., image and/or audiovisual file) for anticipated subsequent use such that the content file need not be re-encoded to add metadata and other data to it. For example, padding may be added to an image file directly after an image file directory, whereby the directory can grow as needed into the padded space. Metadata can likewise be added to the padding, e.g., from the opposite direction that the directory extends into the padding. The padding may be added on the first re-encoding of the file, reducing or eliminating the need for subsequent re-encoding. The padding also may be used to track dead space in the file, with adjacent regions of dead space coalesced into a single region of dead space.

Abstract: A breathing aid for an infant is adapted for delivery of inhalable medication in a gentle flow to an area immediately adjacent the baby's nasal passageway. An oral member formed as a pacifier carries a hollow tube, the open top end of which extends just above the upper rim of the mouth guard of the pacifier. A swivel connector secured to the bottom of the tube allows easy adjustment of the position of the breathing aid in relation to the mouth guard and to a connecting hose, through which oxygen or other medication is delivered.
